Trying the sysctl net.ipv6.conf.all.disable_ipv6=1 workaround for the moment, as it has the least impact in production. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1702910 Title: System freeze after in6_dev_finish_destroy errors Status in linux package in Ubuntu: Incomplete Bug description: After the upgrade to the `4.4.0-83-generic #106~14.04.1-Ubuntu` kernel we are seeing system hangs with the following logs. Prior to this upgrade there were no crashes or kernel traces of this sort. We have ruled out physical hardware issues by moving the VM to another physical host. In the logs there's reference to docker instances on the host. This results in veth devices being brought up and torn down frequently, which is likely related. As a possible workaround we have disabled IPv6 for now. ``` kernel: [337352.274907] vethf317e0d: renamed from eth0 kernel: [337352.386446] docker0: port 1(veth160ed4a) entered disabled state kernel: [337352.393444] docker0: port 1(veth160ed4a) entered disabled state kernel: [337352.395408] device veth160ed4a left promiscuous mode kernel: [337352.395417] docker0: port 1(veth160ed4a) entered disabled state kernel: [337359.301576] vethee2599d: renamed from eth0 kernel: [337359.339582] docker0: port 2(veth3100aab) entered disabled state kernel: [337359.343059] docker0: port 2(veth3100aab) entered disabled state kernel: [337359.344987] device veth3100aab left promiscuous mode kernel: [337359.344997] docker0: port 2(veth3100aab) entered disabled state kernel: [337475.398358] ------------[ cut here ]------------ kernel: [337475.398370] WARNING: CPU: 3 PID: 23671 at /build/linux-lts-xenial-ep3zLI/linux-lts-xenial-4.4.0/net/ipv6/addrconf_core.c:159 in6_dev_f kernel: [337475.398372] Modules linked in: btrfs xor raid6_pq ufs qnx4 hfsplus hfs minix ntfs msdos jfs xfs libcrc32c veth ip6table_filter ip6_tab comment ipt_MASQUERADE nf_nat_masquerade_ipv4 xfrm_user xfrm_algo iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 xt_addrtype iptable_fil filter bridge stp llc aufs tcp_diag inet_diag coretemp crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel ppdev aes_x86_64 lrw gf128mul input_leds serio_raw drm_kms_helper parport_pc drm lp fb_sys_fops syscopyarea sysfillrect sysimgblt vmw_vmci parport shpchp 8250_fintek i2c_piix4 kernel: [337475.398416] CPU: 3 PID: 23671 Comm: kworker/u8:0 Not tainted 4.4.0-83-generic #106~14.04.1-Ubuntu kernel: [337475.398418] Hardware name: VMware, Inc.
